8 Claims.

This invention relates generallyto apparatus for waving human hair and more particularly to improvements of a rod for simultaneously producing a Croquignole and a spiral wave on a lon strand of hair.

The principal object of this invention is the provision of a hair waving rod having independent sections for producing Croquignole and spiral wave forms on a single strand of hair at the same time and wherein the rod sections are permanently secured in assembled relation but are independently revolvable and each section may be locked against turning independently of the other.

Another object is the provision of a single control for selectively rotating one of the rod sections.

Another object is the provision for maintaining the operating mechanism in constant engagement with one of the rod sections.

Other objects and advantages appear in the following description and claims.

In the accompanying drawing a practical embodiment illustrating the principles of this invention is shown wherein:

Fig. 1 is an enlarged plan view of the hair waving rod comprising this invention mounted on a conventional hair clamp.

Fig. 2 is a side elevation of the rod and clamp shown in Fig. 1.

Fig. 3 is an enlarged sectional view of the hair waving rod showing the parts in assembled relation.

Fig. 4 is a view illustrating the Croquignole rod section of the rod with an integral extending sleeve which supports the spiral. rod section.

Fig. 5 is a view illustrating the operating mechanism for independently rotating the Croquignole and spiral rod sections.

Fig. 6 is a view illustrating a modification of the rod section operating mechanism.

Fig. 8 is a longitudinal sectional view of the structure illustrated in Fig. '7 with parts broken away.

Referring to the drawing, It! represents the ed to fit the same character of hair strand clamp II and heating apparatus.

The hair waving rod assembly I0 is made up of the Croquignole or spool section I2 having an integral sleeve l3 extending from one end thereof. The other end of the spool is provided with a narrow cylindrical bearing l4 and a ratchet gear l5 larger in diameter and outwardly adjacent thereto. The spool section and the sleeve are bored out as indicated at It. Immediately adjacent the bearing the bore IB is provided with the cylindrical enlargement H which terminates in an outwardly expanding frustoconical bore l8. The outer end of the sleeve I3 is reduced in diameter as indicated at l9 to receive the washer 20.

The spiral section 22 of the rod is provided with the bore 23 so that it may be rotatably supported on the sleeve I3. The outer end of the bore 23 is enlarged as indicated at 24 to receive the washer .20 which is preferably slightly smaller in diameter than the bore 24. From the outer end of the enlargement 24 the bore is frusto-conical as shown at 25. Thus the extreme ends of the hair waving rod sections are provided with frusto-conical bores l8 and 25 which are employed 'as the driven clutch faces for the separate rod sections.

The perimetral surface of the spiral rod section 22 should be the same diameter as the adjacent end of the spool section and it may taper or be made up of a series of tapered and cylindrical surfaces as disclosed in Letters Patent 2,232,009. The outer end of the rod section is provided with the ratchet gear 26. The teeth of this gear are preferably pointed in the same direction as that of the ratchet gear l5 on the spool section. A small fillet 21 terminating in a Shielding flange 28 is formed between the ratchet gear 26 and the perimetral surface of the spiral rod section to prevent the hair from being caught in the gear teeth.

In assembling the rod sections the spiral section 22 is slipped over the sleeve I3 and the washer 20 is placed on the shoulder I9. An expanding tool is then used to flare out and peen over the end of the sleeve l3, thereby securely holding the washer 24 against the shoulder of the reduced portion I9. This shoulder is cut at the proper spacing from. the end of the spool to allow a slight clearance between the washer 20 and the shoulder formed by the bore enlargement 24 to permit the spool section to freely rotate. This clearance must not be too great or hair may become entangled between the rod sections. To prevent the hair from entering between the rod sections and from entwining around the sleeve |3 an annular flange 30 may be formed on the inner end of the spool section as illustrated in Fig. 3. The end of the spiral rod section is reduced to receive this longitudinally disposed flange. If a hair gets between the end of the flange and the shoulder on the spiral rod section it will not become lodged as readily as it would if permitted to wind around the small diameter of the sleeve l3.

The operating mechanism for rotating the rod sections independently of one another is shown in Fig. 5, wherein the shaft 3| is arranged to be slid through the bore l6 of the spool l2 and the sleeve l3. The frusto-conical clutch member 32 is secured to one end of the shaft 3|. This clutch member is arranged to engage and mate with the frusto-conical bore 25. The other end of the shaft then protrudes beyond the outer end of the spool section 22. A coil spring 33 of a diameter less than the cylindrical bore I1 is slid over the end of the shaft. The second frusto-conical clutch element 34 is preferably formed integral with the thumb handle 35. This element is bored to receive the shaft 3| and may be secured thereto by the pin 36. The clutch 34 is positioned on the shaft 3| to prevent both clutch elements from engaging their respective counterparts at the same time, and the spring 33 is compressed sufficiently to maintain the clutch member 32 in engagement with the spiral section normally but may be compressed to disengage this clutch and engage the clutch element 34 with the spool section of the rod.

The complementary clutch faces may be provided with small longitudinally disposed teeth 31. The movement of the shaft 3| axially should be just sufiicient to clear the teeth on the opposite clutch. With this arrangement driving or rotary force of the operating mechanism may be quickly transferred from one section of the rod to the other and it will not be necessary to hunt for engagement of the clutch elements as required with the dent clutch elements illustrated in Figs. 6, 7 and 8.

The dent clutch elements 49 and 4| are secured to the shaft 3| in the same manner as that described above. The socket elements 42 in the rod sections illustrated in Figs. 7 and 8 are in the shape of a cross, thereby providing four positions in which the clutch elements 40 and 4| may be inserted. Additional slots may be formed to lessen the degree required to turn the shaft 3| for engaging the clutch elements. In order that both clutch members at opposite ends of the rod may not engage at the same time, an enlarged clearance bore 43 is provided adjacent the slots 42.

The hair waving rod may be mounted on the conventional hair clamp l as illustrated in Figs. 1 and 2. The bearing 4 rides in an upwardly open journal 44 in the bracket 45, as does the present Croquignole rod. The opposite end of the shaft 3| lies in the upwardly open journal 46 in the bracket 41.

The ratchet gear I is engaged by the ordinary spring pawl 48 that is supplied with these hair clamps. An additional spring pawl 5|! must be added to the other end of the hair clamp to engage the ratchet gear 26. Thus each ratchet gear is engaged by a separate pawl which aids in holding the rod in position on the journals of the hair clamp and prevents their respective rod sections from becoming unwound. By pushcomplementary ing the spring pawls back from the ratchet gears the rod assembly may be readily removed from the clamp.

The finger 5| which is shaped to fit the Cro quignole spool section for holding the tip of the hair strand may be hinged at either end of the spool form, depending upon which position is best suited to the operator.

It is obvious that the thumb handle 35 may, if desired, be attached to the other end of the shaft 3|, the left end in Fig. 5.
